Guardian angel

The English physician and philosopher Sir Thomas Browne (1605-82) wrote-

'Therefore for Spirits I am so farre from denying their existence, that I could easily beeleve, that not onley whole Countries, but particular persons have their Tutelary, and Guardian Angels: It is not a new opinion of the Church of Rome, but an old one of Pythagoras and Plato; there is no heresie in it, and if not manifestly defined in Scripiture, yet is it an opinion of a good and wholesome use in the course and actions of a man's life, and would serve as an Hypothesis to salve many doubts, whereof common philosophy affordeth no solution.'

'Religio Medici' (1643) part 1 paragraph 33

'The religion of a physician' was placed upon the Papal index in 1645 as forbidden reading for Catholics.
